Patent DE-2406948-A1 (DE)
Title: Doctor blade for screen printer - is movable linearly and pivotally for printing of concave portion adjacent linear portion
Inventor: ALT PETER DIPL ING
IPC: B41F15/44
Filed: 1974-02-14
Abstract: As applied to the printing of the upper surface of a ski, the doctor blade is supported for linear motion along the straight part of the ski by an appropriate slide element including a pivot spaced from the tip of the doctor blade by a distance equal to the radius of curvature of the curved part of the ski. On completion of movement along the straight part the doctor blade is turned about the pivot to print the concave leading end part of the ski. A further pivot near the tip of the doctor blade enables the latter to be raised for the return movement.

Title: Portable multichannel pulse height analyser - includes additional memory to reduce dead time without high power consumption
Inventor: SEYFRIED PETER DIPL PHYS
IPC: G01R19/17
Filed: 1974-02-14
Abstract: The analyser has a main memory with an intermediate memory connected on the input side which stores the amplitude values if a large number of input pulses during one main memory cycle and transmits these values to the main memory. The amplitude values are determined by a classifier. The intermediate memory is preferably a shift register forming part of the classifier with a bit capacity equal to the number of amplitude classes. The power consumption is increased only very slightly and is considerably lower than for analysers with the same dead time having no intermediate memory.

Title: Microtome tissue sections prepn - by rotating spider with sample baskets dipped into successive baths by program control
Inventor: GRUENEWALD AUGUST
IPC: G01N1/36
Filed: 1974-02-26
Abstract: Tissue samples are prepd. for embedding in paraffin, etc. for microtome sections required for histological research, by passing them in turn through dehydration, stabilization and impregnation baths, arranged in a circle. The baskets carrying the samples are suspended from a rotatable spider and are lowered into the respective baths in turn by program control. This allows successive prepn. of the tissue samples in charges as they become available in hospitals or research laboratories. Urgent samples can be treated faster and the labour available is better utilised.

Title: Ice breaker with periodically moving hull - has deckhouse mounted on anti-vibration mountings isolated from hull pitching
Inventor: WAAS HEINRICH DR ING
IPC: B63B35/10
Filed: 1974-06-19
Abstract: The icebreaker is fitted with special drive units near the bows to raise and lower the bows periodically so as to smash the ice. The ship pitches about a transverse axis (15) near the rear of the hull. The whole deckhouse assembly is pivotted about a transverse axis (21) above the pitching axis while the front of the assembly is mounted on vertical dampers and hydraulic rams. These provide a periodic movement to compensate for the pitching of the ship. The system protects the crew from the otherwise uncomfortable pitching, or even higher frequency vibrations which ar required to break the ice.

Title: Furniture castor with two cup-shaped rollers - has rotatable operating member for sprung brake shoe
Inventor: SCREEN STAFFORD THOMAS
IPC: B60B33/02
Filed: 1974-07-23
Abstract: The castor braking means comprises a brake shoe, and an operating member providing a cam surface, the brake shoe being spring-urged towards the cam surface, and the operating member being mounted for rotation about an axis from an "off" position to an "on" position whereby the cam surface is moved to urge the brake shoe against one of the inner surfaces of the roller to effect locking of the roller. Preferably, when the braking means is in its operative position, movement thereof to its inoperative position is restrained, by arranging the cam surface in a manner such that forces acting thereupon do not act to effect movement of the operating member towards its "off" position.

Patent DE-2502713-A1 (DE)
Title: Load lifting mechanism - has ropes forming lattice-work assembly between winch mounting and load support
Inventor: EGGER HERMANN
IPC: B66C13/06
Filed: 1975-01-23
Abstract: The lifting mechanism is particularly for handling irradiation and material testing equipment, using ropes and pulleys to vary the height. The ropes with the winch mounting and the load support form a three-dimensional lattice-work assembly, situated between mounting and support. The winch can actuate four ropes simultaneously. Each rope can have one fall running parallel to the direction of lift, being then reeved round guide pulleys so as to form diagonal falls, and finally anchored to the load support. The design avoids load swining or spinning, and thus allows simply executed yet accurate positioning which can be maintained for a long stretch of time.
Patent DE-2514517-A1 (DE)
Title: Vibration damper for tubular bus bar - has hose contg fluid sections to shift natural frequency
Inventor: SPRICK THEO ING GRAD
IPC: H02G5/00
Filed: 1975-04-03
Abstract: The vibration damper for tubular bus bars is in the form of a tubular hose (3) on the inside of the bar. The hose, which is made from a flexible material such as a plastic, is filled with a fluidic medium (4). One end (7) of the hose is fitted with a feed valve (8), and the other end (6) is closed. The plastic material forming the wall of the hose contains reinforcing elastic and non-elastic material, and the length of hose is divided into sections which can be at regular or irregular distances. The effect of the hose is to introduce forced damping, and thereby eliminate mechanical vibrations, by shifting the natural frequency of the tubular bus bars.
Patent DE-2518657-A1 (DE)
Title: Current limitter for electric traction vehicle - has LC filter on input line and capacitor across supply lines
Inventor: BROM BRUNO CH
IPC: B60L9/00
Filed: 1975-04-26
Abstract: The electric traction vehicle is fitted with an LC filter on the input line, with the capacitor (CE) across the supply lines. In order to prevent the capacitor from being overcharged, due to the larger than supply voltage swing at the input of the capacitor, the inductance (LE) is bridged by a leak resistance (R). The resistor (R) is in series with a thyristor which breaks the leakage connection at set parts of each cycle, and the firing circuit of the thyristor is controlled by a four layer diode (V). The maximum bias on the capacitor is thus clipped to a safe operating value, especially when arcing provides sudden current surges.
Patent DE-2519220-A1 (DE)
Title: Tandem press line with strip feeder - can be operated without changeover as tandem or single press
Inventor: DANGELMAIER KARL
IPC: B21D43/02
Filed: 1975-04-30
Abstract: The tandem press line has a strip feeding system for two presses in which e.g. electric motor rotor and stator lamellae are pressed from the same strip in synchronised succession. The press line is designed so that only one press can be operated on its own without modification of the setting and basic equipment. The strip material (2) is guided after the first press (8) by a transporter (9) which has a strip loop regulator (10). This transporter is stopped when both presses (8, 12) are operating and it is started when only the second press (12) is operated. The strip is fed into the second press by the feeding mechanism (11). In tandem operation on making large components the first press produces blank components which are finished in the second press.

Title: Solar energy heating and hot water system - has temperature stratification in storage vessel to reduce entropy gain
IPC: F24S10/75
Filed: 1975-09-19
Abstract: The system has a storage vessel (1) which contains a fluid suitable for storing heat. This fluid is heated by a heat exchanger (12) immersed in it through which flows primary fluid which has absorbed solar energy in a collector (2). Water for a central heating system is heated in an exchanger (13) immersed in the storage vessel and domestic hot water is heated in an exchanger (14) also immersed in the storage vessel. The vessel is arranged so that the fluid in it is stratified in layers of different temperature and particular care is taken that these layers o not mix. This minimises entropy gain in the system and thus increases efficiency. The output can be controlled by step selection of the appropriate temperature layer.
